U.S. District Judge Gonzalo Curiel has denied a motion to dismiss a Trump University lawsuit

One case is set for trial in November

Washington (CNN)A federal judge on Friday issued a tentative ruling to deny a bid to dismiss a lawsuit by unhappy customers of Trump University.

U.S. District Judge Gonzalo Curiel made the ruling from the bench in San Diego, California, with more motions to be heard in the coming weeks.

The case -- one of two class-action lawsuits by former students of a real estate training program founded by Republican presidential nominee Donald Trump in California -- is set for trial in November. A message left with Trump's presidential campaign was not immediately returned.

This latest development is part of an ongoing saga for Trump after he came under fire in June for questioning Curiel's impartiality based on his Mexican heritage.

Trump University was launched in 2005 as a real estate seminar business that promised to teach students Trump's investing techniques.

The business, which has effectively been defunct for several years, is facing three lawsuits filed by and on behalf of dissatisfied enrollees, two class actions in California and a lawsuit by New York Attorney General Eric Schneiderman.

The plaintiffs allege Trump's program took in an estimated $40 million, but was mired in fraud and deception. Trump has defended the school and said the lawsuits should have been dismissed.
